Porter Gage is a possible companion for the Sole Survivor in the Fallout 4 add-on Nuka-World.

Porter Gage grew up in a small farming settlement with his parents, watching them give in to raider demands without a fight. When he was twelve and they were raided once again, he used this chance to run away from his home to avoid following in his parents' footsteps.

The next few years, Gage survived by taking odd jobs, doing what he could to earn caps. Later, he turned to caravan and mercenary work; however he still saw people giving in to raiders, and realized something about the raider way of life: he wanted to be one of them. After the raid of a settlement he had been residing in, he joined the raiders at 16 years old.

The first gang he joined was a decently sized group which apparently had a lot of strength, but wasn't using it wisely. Being young and naive, he attempted to suggest different ways the gang could be improved and streamlined. Eventually he was approached by his boss, Connor "The Harvester" (a name Gage thought was laughable), who actually listened to Gage, much to the latter's surprise. After this, Connor would return to Gage for advice and opinion on his plans, telling him how much he trusted him which, in turn went straight to Gage's head.

After a year of working alongside Connor's gang, Gage and Connor decided​ to try and make peace with another nearby gang. Meeting on neutral ground, they worked out who would do the negotiating and what would happen if things should go wrong. Gage volunteered to take point for the negotiation with three of their biggest crew mates backing him up, and he was chosen.

An hour into the negotiation, the rivals began to come around, saying the truce was in their best interest. However, before Gage knew it, there was gunfire and explosions. He began to panic, thinking that Connor would have to come and bail them out. He soon realized that Connor had set him up for death. Connor, in Gage's mind, must have begun to fear him, thinking he had "pumped" out all of the good information and that Gage would usurp Connor's role. Connor had used Gage as a distraction so he and his men could ambush both Gage and the rival gang. Gage survived the encounter and escaped on his own.

Gage debated going back to his former boss and his gang with guns blazing and revenge in mind, but he knew that that would lead to certain death. Instead he moved on, vowing he would never be so stupid, or so trusting, again. Gage has said that he has been in many gangs and has witnessed each one destroy itself from stupidity, laziness and chem usage, stating that he bolted before their end occurred.
